The concept of industrial heritage arose in the middle of 20th century, when several industrial buildings and urban landscapes were destroyed in the UK. Since then, numerous efforts have been put to recognize industrial heritage works. Industrial sites are considered as a milestone in human history; they contain memories from a period which was a nuisance, and at the same time symbolized hope toward a better life. Through their architecture, industrial buildings represent technological developments of countries, and the socio-cultural values of their own period.
Loss of their industrial uses within cities, and their unsuccessful social status put these buildings on the verge of destruction. A shift in the mainstream attitude in terms of work and activities, and an architectural style originating from universal experience highlight the importance of investigation and preservation of these buildings. This is where the knowledge to preserve those building which are unable to secure their own prosperity gains importance. The reason of this inability comes from the fact that these buildings are no longer needed, which turns them into abandoned and unsafe spaces, endangering well-being of the society. Adaptive reuse of an existing historical building and adding an extension to it will create movement, liveliness and visual diversity, while maintaining the building character. Enormous scale of the factory, the rhythmic repetition, the length which points to the infinity and even melancholic colors are key points when seeking for an authentic design in order to reuse the building.

In investigation of production technology and provenance studies of historical objects as well as to propose and develop strategies for restoring and conservation, it is necessary to get information about studied samples. This information is different according to the type and kind of materials of historical objects.
Today, identify and accurately determine the elemental composition and constituent material of given sample is one of this essential information that be able to measure using modern laboratory instruments In this paper, was presented some results was obtained in past few years from different historical and cultural objects using micro ion beam analysis in Van de Graaff laboratory of Nuclear Science and Technology Research Institute.
Investigation of Painted enameled potteries to determine the different pigments used in, determine the thickness and purity of the gold layer in gilded enameled potteries, determine the responsible elements to brightness of wall painting in a historical place, Investigate the causes of corrosion and degradation of an old manuscript, determine purity of Elymais bronze coins and determine the type of Iranian historical and ancient glasses are some studied objects that will be presented in this paper.
The results of these analysis will significantly help to investigate the production technology, to determine the authenticity of the samples and finally to use in restoration of these historical objects.

Haj Saleh Bathhouse, located in the historical fabric of Saqqez city, dates back to the Zand period. Its entrance is situated in the city's traditional bazaar. The construction style of the building is Isfahani and features unique stucco decorations. One of the notable and significant stucco reliefs in the bathhouse is the hunting scene, which has undergone extensive deterioration. This relief consists of three layers: two lime-based layers and one paint layer.
In this study, through laboratory examination, the materials used in the stratigraphy of the relief were technically identified. Subsequently, the deterioration patterns affecting the artwork were analyzed. The conservation and restoration process of the hunting scene is also detailed: following mechanical and chemical cleaning, delaminated areas were consolidated using an injection method. A slurry made from dental gypsum combined with 5% Plextol in water was injected with the aid of a pillow (bladder) technique to reattach and strengthen the lifted layers.
The missing parts were reconstructed using a mixture of gypsum and 5% Plextol, followed by chromatic reintegration with watercolors to match the surrounding areas and faded pigments. Finally, the entire artwork underwent final consolidation using 5% Plextol solution.

Historical and cultural relics made of paper are among the most important artifacts of any culture and civilization and are valuable from a historical, artistic, scientific, economic, technical, and religious perspective. All paper materials change over time, so that this process cannot be completely stopped, but the speed of change can be controlled with conservation and restoration operations.
The manuscript studied in this research is a manuscript document belonging to the year 1287 AH, and the Qajar period.
The purpose of this research is to examine the used materials, pathology and finally to present a restoration plan for this manuscript. In this regard, after examining library resources, the fibers, glue, and materials used in the document were identified using laboratory studies, the type of ink used, and other tests for this document. Tests showed that the fibers of the document are wood and the sample contains a small amount of lignin, and the presence of starch and sugars was confirmed in the paste test. The acidity of the paper is 45.5 and the ink used in the document is of the metal-mazonite type and is sensitive to water. After completing the restoration stages of the document, the document was delivered to its owner.

 Why should a specialized authority for artifact authentication—specifically in the fields of antiques, gemstones, and manuscript heritage—be established within the Official Experts Association of the Judiciary? And why should this authority, regardless of time or institutional fluctuations, most be reserved exclusively for certified experts with an academic degree in the conservation of historical, artistic, and cultural objects?

To preserve valuable architectural works, the first step is to have a complete and comprehensive understanding of these works. Among the valuable parts of architectural works are their decorations and murals. Canvas murals are a type of mural that differs from regular and continuous murals in terms of materials, execution method, and generally in nature. Considering that the first step in preserving a work of art is its understanding and perception, the difference between these works is such that carrying out the usual methods of conservation and restoration (without a correct understanding of the work) will damage their authenticity and integrity. In the research conducted on the subject of canvas murals, some researchers place these works in the group of paintings on canvas, and some researchers also recognize these works as murals, and there is insufficient knowledge in this field. The restoration theories that have been presented and published at the national and international levels have references to the preservation and restoration of historical paintings, but they have not directly mentioned how to preserve and restore canvas murals. In order to reach the theoretical principles and foundations of the preservation and restoration of this type of murals, it is necessary to examine international charters, theories, and guidelines in the field of the preservation of historical paintings so that, according to these theories and also the studies that are carried out in the field of identifying the criteria for the preservation of canvas murals, it is possible to systematically recognize, restore, and display canvas murals correctly. In this article, the constituent layers of historical Iranian murals are first introduced, and then the results of the studies of written sources in the theoretical field of the restoration of historical paintings are presented. In fact, these studies and discussions are an introduction to the preservation and restoration of Iranian canvas murals.

Modern management has increasingly attracted the attention of executive and organizational systems in recent decades. The application of its key components, such as systems thinking, contingency decision-making, the importance of leadership and effectiveness, goal and strategy setting, motivation, and self-regulation, constitutes part of the success factors for today’s human resource managers.
Preservation, restoration, and protection of historical buildings are among the fundamental objectives in the field of cultural heritage. This descriptive–survey study, conducted through a qualitative–analytical method and based on the author’s field experience in supervising 25 projects on the conservation, restoration, and documentation of architectural decorations in historical buildings across Khorasan Razavi province between 2007 and 2016, demonstrates that restoration teams are often composed of academic experts, traditional craftsmen, or a blend of related competencies, each possessing a unique insight and professional commitment to the authenticity of the buildings.
Managers who identify the most qualified individuals and adopt a participatory management approach not only achieve better outcomes in the given projects but also ensure job satisfaction, productivity, synergy, and the professional growth of their teams. Furthermore, they establish sustainable career paths and create opportunities to train and nurture skilled groups for future specialized projects.

The expansion of the scope of ideas and discussions of conservation and restoration, as an interdisciplinary field, in today's world is in harmony with the growth of science in other branches and fields. This movement and flow cause new categories and concepts to enter the theoretical foundations and literature of this field every day. The birth of new ideas and concepts itself causes a change in the view of issues that previously seemed obvious and unchanged. The nature of the movement towards expanding the boundaries of thought and considerations in the science of conservation and restoration leads to the emergence of new perspectives and the proposal of new issues that, in turn, can be effective in judging and evaluating the measures designed and carried out. Studying and reflecting on the new ideas and perspectives raised in the field of conservation and restoration of historical-cultural objects shows a large gap in the country's collection of awareness and knowledge of conservation and restoration regarding the relationship between the audience and the restorer, which was the main factor in choosing and addressing the subject of the present article. On the other hand, some have pointed out that building an audience is not a one-time thing. An audience is always subject to loss and gain, and as a result, a direct and lasting relationship between the artist and his audience is essential. By measuring each of these factors in Iran, we encounter shortcomings in the audience-building process, especially in the field of cultural heritage.
